Study of the eHWC J1825-134 at the Highest Energy with HWAC

eHWC J1825-134 is one of the brightest Galactic 𝛾-ray sources above 50 TeV observed by High Altitude Water Cherenkov 𝛾-Ray Observatory (HAWC). Detailed morphological studies have revealed a new point-like source inside this region with a spectral energy distribution extending beyond 200 TeV without any cutoff. These very-high-energy 𝛾 rays emission can originate from leptonic or hadronic processes. The new point-like source is located in a region containing PWNe and a high-density giant molecular cloud [MML2017]99. If the source emission is associated with the hadronic scenario the TeV 𝛾 rays may have been produced by cosmic rays colliding with ambient gas. If this were the case, eHWC J1825-134 is an indicator of the existence of a galactic PeVatron in the region that accelerates particles up to PeV energies.
